问题描述
hi dudes
i在类文件中有这个代码：
hi dudes
i have this code in class file:
ublic class MainActivity extends ListActivity {
DBAdapter db;
List <Story> storyList;
ListView lvMain;
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.i("#%%%%%%%%%%%%%%%%%%%%%","1");
super.onCreate(savedInstanceState);
Log.i("#%%%%%%%%%%%%%%%%%%%%%","1.5");
setContentView(R.layout.activity_main2);
Log.i("#%%%%%%%%%%%%%%%%%%%%%","2");
db.open();
storyList=db.GetAllItems();
Log.i("#%%%%%%%%%%%%%%%%%%%%%","3");
if (storyList.size()==0)//import database if local database is empty.
{
Log.i("#%%%%%%%%%%%%%%%%%%%%%","4");
InputStream sourcePath;
OutputStream destPath;
try {
sourcePath = getBaseContext().getAssets().open("StoryDB");
destPath=new FileOutputStream( "/data/data/"+getPackageName()+"/databases/data");
Log.i("#%%%%%%%%%%%%%%%%%%%%%","5");
CopyDB(sourcePath,destPath);
Log.i("#%%%%%%%%%%%%%%%%%%%%%","5.5");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i(DBAdapter.TAG,"@@@DB copy finished.");
storyList=db.GetAllItems();
}
}
和xml文件（activity_main）我有这个：
and in xml file (activity_main) i have this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/button1"
android:layout_toRightOf="@+id/button1"
android:text="Button" />
<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/button2"
android:layout_toRightOf="@+id/button2"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="25dp"
android:text="Button" />
<ListView
android:id="@+id/lvMain"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button1"
android:layout_below="@+id/button1"
android:layout_marginTop="14dp" >
